Builds a new list by adding items to either end of an input list. Use it to fold a value into a list without leaving the data engine — for example, building a list of order lines inside a Flow Each loop.

​
Inputs

  • List — the starting list. Leave unwired to start from an empty list. A nil value coming in is also treated as empty.
  • Prepend — item to put at the start of the list. Leave unwired to skip prepending.
  • Append — item to put at the end of the list. Leave unwired to skip appending.
Connecting both Prepend and Append in the same node is allowed — the prepend item lands first, the append item lands last, all in one shot.
